The photochromic ImpactX2 lenses are guaranteed to be unbreakable for life. These lenses achieve a unique color from an initially transparent state, which darkens or clears depending on the varying light conditions. ImpactX is a family of optical polyurethane polymers with semi-rigid properties. The ImpactX lenses are available in three different colors (Black, Red, and Purple), each with a mirrored version.
